ticularly in connection with municipal work requiring the handling of scattered piles of material. 4

Referring more particularly to the drawings, l have illustrated my improved loading apparatus as comprising a supporting carriage, tractor or the like 1 consistingof the usual frame 2 carried by supporting wheels 4. While the carriage 1 is adapted to be moved in any desired manner, I may provide the same with a mot r 5 transmit ting power to the rear supporting Wheels 4: through adifferential mechanism 6. The

'0 all whom it may concern:

Be it known that I, FRANCIS LEE STUART, a citizen of the United States, residing at lVashington, in the District of Columbia, have invented certain new and useful Improvements in Loading Apparatus, of which the following is a specification.

This invention relates broadly to apparatus for handling material in bulk, and more particularly to a portable reclaiming or loading apparatus comprising an elevator and having scraper plows cooperating therewith for bringing the material into operative position with the conveyor.

The principal objectof thepresent invendevices of this general nature, is adapted to tion is to provide a portable loading appaequalize the dr1vin force during the passage of structions or the like.

Extending transversely of the frame 2 is a conveyerframe 7 supporting an endless conveyer 8 passing around tripper roll 9 located adjacent the upper end of the conveyer frame, and around a guide roll 10 adjacent the lower. end of the rrame. The conveyer may be driven by'any suitablesource of. power 11 through gearing 12 and a sprocket chain or its equivalent 14 in operatlve engagement with the upper tripper roll. It will be obvious that upon operation of the conveyer the material carried thereby Will be discharged over the tripper roll into a wagon or other vehicle 15 which it is desired to load.

in its preferred form, the conveyer frame has a pivotal mounting 16 in the carriage frame 2, and is provided with a lifting mechanism comprising chains or cables 17 adapted to be taken up or played out by the shaft 18 when operated bythe hand wheel 19.

The lower end of the conveyer frame is provided with scraper plows 20of the type disclosed and claimed in my copending application Serial No. 208,598, filed December 24, 1917. These scraper plows preferably carrier so that the same may be moved from place to place as desired.

A further object of the present invention is to provide means for adjusting the'loading conveyor so that the same mayenter the pile of material being handled at various heights.

The foregoing and other objects, together with their attendant advantages, will be apparent as the invention becomes understood by reference to the accompanying specification and drawings forminga part thereof, throughout the several views of Which like characters of reference are used toindicate like parts.

Referring to the drawings, Figure-1 is a side view of my improved loading apparatus.

In handling materials in bulk, such as coal, ore, gravel, and the like, it is customary to transfer the material from a main source of supply into a plurality of storage piles which may be scattered at some distance. one from the other. It is the primary purpose of the present invention to provide a portable loading ap aratus which may be of the convcyer frame to which-they are detachably secured by means of suitable fastenings 21. A curved mold board or edge piece 22 is provided on the outer edge of the scraper plows for cotiperating with the material M being loaded so as to guide the same onto the elevating conveyer.

In operation the supporting carriage is moved to'desired position adjacent a pile of terial from the storage piles. An apparatus of the type herein disclosed is useful pardifi'erential mechanism, as is customary inthe supporting carriage around ob extend in opposite directions from the sides conveyer, as described, which extends transversely to the direction of travel of the scraper plows, the stability or slope of the pile of material is destroyed so that it gravitates onto the conveyer by which it is loaded into the vehicles provided. I

It frequently happens that due to irregularities in the surface on which the material is piled that it becomes necessary to cause the scraper plows to entcrthe pile of material at different elevations. This may be readily accomplished by the lifting mechanism referred to. This adjustment is also valuable in reclaiming or loading material which is disposed on a level either above or below that on which the carriage 1 is travcling.

It will be obvious that the elevating conveyer may be in the form of an endless belt, bucket conveyer, or any other well known type, and that changes may'beunade in the structural embodiment of the apparatus disclosed within the scope of the appended claim.

WVhat I claim is:

A portable loading apparatus, comprising a movable supporting wheeled carriage, a scraper plow projecting from and arranged wholly beyond the side of the carriage and its wheels and which is supported on its inner side only, a conveyer belt extending at its outer end across the rear portion of the plow, but having both its receiving and return portions below the level of the bottom I of the plow, a roller carried by the plow around which the lower end of the belt extends, said conveyer belt having its upper end extending beyond the opposite side of the carriage, and means for driving the con veyer.

In testimony whereof I have hereunto subscribed my name.

FRANCIS LEE STUART.
